I found this article interesting:

It is about an EEG headset that uses solar power and body heat to power itself.

I am most interested in the headset itself. It is a lightweight product that looks like headphones.

This is interesting because an EEG can read the electrical activity of the brain. If it works properly, it could be a very precise measurement of sleep, thus knowing exactly what stage of sleep the sleeper is in. I could see this being like a new and improved NovaDreamer.

Current LD equipment relies on sensing eye movements. I am not sure how reliable it is but I would think that EEG equipment would be nearly the most reliable means of determining the state of dreaming.

I really hope Laberge and his team work on something that manipulates this technology.

On a side note: I could also see this being an excellent tool for gaming, as the article suggests.
